LEED for Neighborhood Development awards points for restoring impaired natural habitats. The goal is ecological uplift, improving the site’s ecological value beyond its pre-project, degraded condition. While a stormwater function is beneficial, the primary credit intent is ecological restoration. Avoidance or off-site mitigation does not directly restore the on-site habitat and typically yields fewer points in the ND context.

The Smart Location and Linkage prerequisite fundamentally requires that the project be located within a certain walkable distance (typically 1/2 mile) of existing or planned transit stops. Internal neighborhood design features like street networks and mobility hubs are valuable for other credits, but the prerequisite is specifically about the project’s location relative to existing community infrastructure and transit.

For the LEED ND Density credit (GIBc4), density is calculated as the total of dwelling units plus non-residential square footage divided by 1,000 (to convert to equivalent units), all divided by the total project site area. The total project site area includes all land within the project boundary, regardless of whether it is built upon, paved, or protected open space. The credit intent is to measure the overall efficiency of land use for the entire parcel.

LEED ND emphasizes district-scale systems and strategies that go beyond what individual buildings can do alone. A centralized non-potable water system is a prime example of a shared infrastructure solution that can achieve significant potable water savings across the entire project, aligning perfectly with the neighborhood development scale. While building-level certifications are good, they do not necessarily leverage the collective efficiency gains possible at the district level.

The most effective and legally sound method for a master developer to ensure district-wide performance is to embed the green building requirements into the governing documents for the project, such as covenants, conditions, and restrictions (CC&Rs), or land disposition agreements. This creates a binding obligation on all future builders and owners, making the credit achievable and enforceable. Relying on design intent or excluding buildings undermines the credit’s goal of comprehensive neighborhood sustainability.

The Brownfield Remediation credit (SLLc5) is specifically designed to encourage the cleanup of contaminated sites. The act of remediating contaminated soil—whether through on-site or off-site methods—to meet health-based standards is the core activity that earns points under this credit. It is not a prerequisite; it is a point-earning opportunity that turns a liability into an environmental and community benefit.

The intent of compact development in LEED ND is not just raw density, but creating walkable, efficient, and context-sensitive neighborhoods. Clustering density in a mixed-use, pedestrian-friendly core promotes walking, reduces vehicle trips, and supports transit. It also demonstrates sensitivity to the surrounding context by providing a transition in scale, which is a key aspect of good neighborhood planning. The other options create density but fail to create a quality, connected, or context-appropriate urban form.

In dense urban settings, the conflict between tree root zones and underground utilities (and sidewalks) is a major, real-world challenge. LEED ND recognizes this. A viable, best-practice strategy is to use engineered solutions like structural soil cells or suspended pavements that provide both a stable pavement surface and adequate soil volume for healthy tree growth. The other options are not best practices; artificial structures don’t provide ecological benefits, planting fewer trees reduces overall benefit, and evergreens may not be appropriate for all climates or design goals.

While lighting is important for safety and is addressed in other credits (like the Light Pollution Reduction credit), the Pedestrian-Friendly Streets credit (GIBc9) focuses primarily on the physical design and connectivity of the street network. Its key requirements involve connectivity (short block lengths), accessibility, and active edges (transparency and building orientation). Specific, prescribed lighting levels are not a primary metric for this particular credit, making it the least critical item among the choices for achieving its specific intent.
